Superwool XTRA Paper is manufactured using our patented Superwool XTRA composition and technology. Superwool XTRA Paper, our newest innovation does not form respirable crystalline silica and is designed to offer excellent performance in demanding high temperature applications. Superwool XTRA has excellent thermal and mechanical insulation properties and handleability is exceptional. Extreme flexiblility and high tensile makes Superwool XTRA Paper ideally suited to applications requiring further processing (laminated composites, die-cutting, rolling, folding as examples). Superwool XTRA Paper provides stability and resistance to chemical attack and is unaffected by incidental spills of oil or water. Thermal and physical properties are restored after drying. An organic binder burns out cleanly at approximately 300°C (572°F) upon initial firing, with ignition starting at 180°C (356°F). Features • Excellent thermal stability results in reliable and consistent thermal insulating performances: ◦ Very low thermal conductivity ◦ Immune to thermal shock ◦ Low heat storage • No formation of respirable crystalline silica when exposed to high temperatures • Excellent resistance to chemicals and pollutants, especially alkali metals • No reaction with alumina based bricks in application in the range of the typical use temperature • Low Shot fibre which provides a smooth surface finish with improved handleability ◦ Excellent tensile strength results in: ◦ Strong resistance to tearing ◦ Excellent flexibility ◦ Easily die-cut to form complex shapes for high temperature gasketing
